This handy tool is like a bevel gauge with the addition of a protractor scale - essential for when you need to hit a specific angle. Use it to transfer angles from a pattern to your saw or jointer, or as a marking gauge. It’s graduated from 0° to 180° in both directions so you can quickly convert inside angles to outside angles. Simple to use; just loosen the knob to adjust. The anchored lock washer prevents the bar from shifting as it’s tightened. Deeply etched scale lines won’t wear off. Machined from stainless steel. Protractor head measures 2" x 3-1/2". Measures 7-3/4" long at 90°.
